DDTBFDCHK is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Control String for Table Checks (Fields)" Information within sap ABAP programs.

This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.

i.e. DATA: wa_DDTBFDCHK TYPE DDTBFDCHK.

The DDTBFDCHK table consists of various fields, each holding specific information or linking keys about Control String for Table Checks (Fields) data available in SAP. These include SAA_SPACE (Test: Does name exist?), SAA_LENGTH (Test: Is name too long?), SAA_CSPACE (Test: Does name contain blanks?), SAA_HYPHEN (Test: Does name contain '-'?)..
